Why are external style sheets preferred?

Using an external style sheet has the advantage of storing everything in a single file. All other pages that make reference to the stylesheet will automatically update or reflect changes once they are made. This makes maintaining bigger websites simpler

Utilizing external style sheets is unquestionably preferable because it will make it easier for you to recall the style you applied to the div (s). Because a page will load more quickly with less HTML code, the loading time is decreased.
